[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1-5 As shown, this specific embodiment adopts the following technical solution: it includes a base 1 and a worktable 2, with the worktable 2 provided above the base 1;

[0027] It also includes:

[0028] A rotating seat 3 is rotatably mounted on the upper right side of the machine base 1 via a shaft and bearings. A movable seat 4 is located on the left side of the machine base 1. A motor 5 is fixedly mounted on the left side wall of the movable seat 4. Mounting cylinders 6 are rotatably connected to both the rotating seat 3 and the movable seat 4 via bearings. The output shaft of the motor 5 is fixedly connected to the mounting cylinder 6 on the left side. A spring 20 is fixedly mounted in a cylindrical groove at the bottom of the rotating seat 3. A limit block 21 is fixedly mounted on one end of the spring 20. Two limit blocks that cooperate with the limit block 21 are located on the upper part of the machine base 1. The groove 22, through the rebound thrust provided by the spring 20 to the limiting block 21, can realize the contact of the limiting block 21 in the limiting groove 22, thereby realizing the limiting function of the rotating seat 3 in different rotational positions. The upper part of the machine base 1 is provided with an arc-shaped groove 23 that communicates with the two limiting grooves 22, and the arc-shaped groove 23 is matched with the limiting block 21. The arc-shaped groove 23 can not only guide the movement of the limiting block 21 during the rotation of the rotating seat 3, but also reduce the wear generated during the movement of the limiting block 21.

[0029] Positioning strips 7, of which there are several, are distributed in two mounting cylinders 6 with equal rounded corners. A polishing roller 8 is suspended above the base 1. Both ends of the polishing roller 8 are movably inserted into the two mounting cylinders 6. The end of the polishing roller 8 is provided with a positioning groove 9 that cooperates with the positioning strips 7. A threaded locking rod 17 is threadedly inserted into the mounting cylinder 6 on the right side. One end of the threaded locking rod 17 is movably inserted into the groove 18 opened on the polishing roller 8. The threaded locking rod 17 can realize the connection limit between the polishing roller 8 and the right mounting cylinder 6, and prevent the polishing roller 8 from falling off the right mounting cylinder 6 during the rotation of the rotating base 3.

[0030] The threaded adjusting rod 10 is rotatably mounted on the movable seat 4 via a bearing, and is also inserted into the machine base 1 via a threaded rotation. Guide rods 11 are fixedly provided on both the front and rear sides of the right side wall of the movable seat 4, and the guide rods 11 are movably inserted into the machine base 1.

[0031] A protective cover 12 is installed above the polishing roller 8. A first connecting frame 13 is fixedly installed on both the left and right sides of the rear side wall of the protective cover 12. Two second connecting frames 14 are fixedly installed on the upper part of the machine base 1. The first connecting frame 13 is located inside the second connecting frame 14. A rotating shaft 15 is fixedly installed on the first connecting frame 13. The rotating shaft 15 is rotatably installed on the second connecting frame 14 through a bearing. A linkage mechanism 16 connected to the left rotating shaft 15 is provided inside the machine base 1. Support blocks 19 are fixedly installed on the opposite side walls of the moving seat 4 and the rotating seat 3. The protective cover 12 is abutted against the support blocks 19. The support blocks 19 can provide auxiliary support for the protective cover 12, thereby improving the stability of the protective cover 12 above the polishing roller 8.

[0032] The linkage mechanism 16 includes:

[0033] Rack 16-1, the rack 16-1 is fixedly mounted on the guide rod 11 on the rear side, and a linkage rod 16-2 is rotatably inserted into the machine base 1 through a bearing. The lower end of the linkage rod 16-2 is fixedly sleeved with a spur gear 16-3 that meshes with the rack 16-1.

[0034] The first bevel gear 16-4 is fixedly sleeved on the rotating shaft 15 on the left side. The upper end of the linkage rod 16-2 is movably inserted into the second connecting frame 14 and fixedly sleeved with the second bevel gear 16-5. The first bevel gear 16-4 and the second bevel gear 16-5 are meshed. When the moving seat 4 is moved to the left so that the left end of the polishing roller 8 is disengaged from the mounting cylinder 6 on the left side, the protective cover 12 can be flipped synchronously through the cooperation of the rack 16-1, linkage rod 16-2, spur gear 16-3, first bevel gear 16-4 and second bevel gear 16-5, so as to completely expose the polishing roller 8, thereby making the loading and unloading of the polishing roller 8 more convenient.

[0035] When using this utility model, the threaded adjusting rod 10 can be rotated to move the movable seat 4 to the left. The movable seat 4 drives the left mounting cylinder 6 and guide rod 11 to move to the left, causing the left mounting cylinder 6 to disengage from the left end of the polishing roller 8. The guide rod 11 drives the rack 16-1 to move to the left. The meshing of the rack 16-1 with the spur gear 16-3 causes the linkage rod 16-2 to rotate. The linkage rod 16-2 drives the second bevel gear 16-5 to rotate, which in turn drives the first bevel gear 16-4 to rotate. The first bevel gear 16-4 then drives... The left rotating shaft 15 rotates, and the left rotating shaft 15 drives the protective cover 12 to flip to the rear through the left first connecting frame 13, so that the polishing roller 8 is fully exposed above the machine base 1. Then the rotating seat 3 can be rotated so that the polishing roller 8 is rotated to the outer position above the machine base 1, making it easier for the staff to load and unload the polishing roller 8. Then the threaded locking rod 17 is rotated. After one end of the threaded locking rod 17 is disengaged from the groove 18, the polishing roller 8 can be moved away from the right mounting cylinder 6 to realize the disassembly of the polishing roller 8 from the right mounting cylinder 6.

[0036] Compared with the prior art, the beneficial effects of this utility model are:

[0037] 1. With the cooperation of the linkage mechanism 16, when the moving seat 4 is moved to the left so that the left end of the polishing roller 8 is detached from the mounting cylinder 6 on the left, the protective cover 12 is flipped at the same time, so that the polishing roller 8 is fully exposed above the machine base 1, making the loading and unloading of the polishing roller 8 more convenient.

[0038] 2. Through the cooperation of the rotating seat 3, spring 20 and limiting block 21, the polishing roller 8 can be rotated to the outer position above the machine base 1, and the position of the polishing roller 8 after rotation is limited, which further improves the convenience of loading and unloading the polishing roller 8.

[0039] 3. The support block 19 can provide auxiliary support for the protective cover 12, thereby improving the stability of the protective cover 12 above the polishing roller 8;

[0040] 4. The connection between the polishing roller 8 and the right mounting cylinder 6 can be limited by the threaded locking rod 17, which prevents the polishing roller 8 from falling off the right mounting cylinder 6 during the rotation of the rotating seat 3.

[0041] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
